Abstract: Wolf (Canis lupus) populations have recovered and expanded across many parts of the world thanks to conservation efforts, including improved legal status and restoration of their prey. Concurrently, public concerns regarding the risk of wolf attacks on humans and livestock are increasing as wolves occupy human-dominated landscapes. We examined a unique case in Europe allegedly involving wolves in the death of a female British tourist, aged 64, in northern Greece in September 2017. This incident received extensive international media attention and yet many fundamental details of the case area are lacking, including whether local livestock guarding dogs played a role. To assist in resolving the case, we conducted an extensive literature review which documented 13 criteria linked to the risk of either a wolf and/or a dog attacking a human. We also conducted a camera trap survey (October to December 2017) soon after the fatal attack to calculate the activity overlap among humans, dogs and wolves. Sufficient data were available for assessing 11 of the 13 criteria. For the remaining two, the required data were either not analysed (i.e. canid DNA collected from the attack site), not appropriately collected (i.e. DNA from the mouths of suspected dogs) or were collected, but misinterpreted (i.e. the post-consumption patterns of the victim’s corpse). Via this combination of evidence, we conclude that this case involved a fatal dog attack. This assertion is supported by evidence such as the: a) high dog-human activity overlap at the attack site which peaked during the attack time as opposed to near zero wolf-human activity overlap at the same time, b) presence of a large pack of unsupervised dogs, c) high ratio of male dogs in the dog pack, d) close vicinity of the attack site to dog owner’s property and e) previous documented aggression of these dogs towards humans. The consumption patterns, time scale and location of the victim’s remains indicate a posthumous consumption of the corpse possibly by the same dogs and/or by wild scavengers including wolves. A multidisciplinary approach, such as this one, in the assessment of putative wildlife attacks on humans can reduce misidentifications of the responsible species by forensic authorities and, therefore, prevent unfounded decrease in public tolerance for large carnivores.

Do the roadkills of different mammal species respond the same way to habitat and matrix? https://natureconservation.pensoft.net/article/73010/ Nature Conservation 47: 65-85

Abstract: While road network expansion connects human settlements between themselves, it also leads to deforestation and land use changes, reducing the connectivity between natural habitat patches, and increasing roadkill risk. More than 30% of registered mammal roadkills in Brazil are concentrated in four species: Cerdocyon thous (crab-eating fox); Euphractus sexcinctus (six-banded armadillo); Tamandua tetradactyla (collared anteater) and Myrmecophaga tridactyla (giant anteater), the latter being categorized as vulnerable by IUCN redlist. Our aim was to understand how these animals’ roadkills could be related to the land use proportions on landscapes all over the Brazilian territory, and investigate if the roadkill patterns differ among species. We collected secondary data on mammal roadkills (N = 2698) from several studies in different regions of Brazil. Using MapBiomas’ data on land use and land cover, we extracted landscape composition around each roadkill sample. Through the proportion of land use and land cover in the area of influence where the roadkill occurred, we built binomial GLM models and selected the best ones by Akaike Information Criteria. For crab-eating fox and the six-banded armadillo, the best models include matrix coverage resulting in increased roadkill risk, while both anteaters’ species have a habitat and a matrix component in their best models, with an interaction between the variables. These four species seem to be roadkilled in different landscape arrangements, but in all scenarios, anthropic areas had an important influence over the models. For habitat-dependent and more sensible species, such as Tamandua tetradactyla and Myrmecophaga tridactyla, the amount of matrix influencing the roadkill risk depends on habitat availability in the landscape. It changes the strength and direction of the effect according to the proportion of natural areas in the region, while with generalist species such as Cerdocyon thous and Euphractus sexcinctus, the quantity of human-modified coverage increases the risk.

Matching social-ecological systems by understanding the spatial scale of environmental attitudes https://natureconservation.pensoft.net/article/28289/ Nature Conservation 30: 69-81

DOI: 10.3897/natureconservation.30.28289

Abstract: Mismatching in the spatial scales of social structures and ecological processes complicates the management of natural resources. Here we suggest the use of variance components to determine at which spatial scale variation in feelings, environmental attitudes and value orientation is largest and hence most exposed to conflicts. We estimated the variance components of the feeling of fear for large carnivores, environmental attitudes towards large carnivores and environmental value orientation at 3 scales (municipality, county and country) in Norway and Sweden. The feeling of fear for specific carnivores had the highest variance components at the municipality level, we found no specific scale that best explained the variance in attitudes towards carnivores in general, while attitudes based on environmental value orientation showed the highest variance components at the country level. To match the social-ecological systems, we conclude that management units have to be designed as the best possible trade-off between the social and ecological scales; i.e. largest possible to maintain ecological sustainability, but small enough to maintain a low degree of social conflicts.
